About this service
Irrigation design
A well-maintained landscape depends on irrigation that delivers water in the right amounts and to the right places. An irrigation system designed without reference to the planting plan, or one that does not account for the drainage and soil conditions on the property, creates more problems than it solves. Peter Howe Design designs irrigation systems that are integrated with the landscape from the beginning.
Whether the system is part of a new installation or is being added to an established property, the design process begins with an assessment of the site conditions and a review of what the plantings actually need. Coverage, drainage, and seasonal adjustment are all part of the plan before any pipe is laid.

What we offer
System layout and design
We design the full irrigation system, including zone layout, head placement, pipe routing, and controller specification. The design is built around the property as it exists, and it accounts for terrain, soil type, and plant water requirements.
Integration with planting plans
We coordinate the irrigation design directly with the landscape planting plan, so the coverage matches what was actually planted rather than a generic grid. Trees, shrubs, turf, and beds each receive appropriate coverage without overlap or gaps.
Monitoring and seasonal adjustment
We monitor the irrigation system and adjust the seasonal programming as conditions change through the growing season and into the fall shut-down, so the system continues to run efficiently.
System audits for existing properties
We assess existing irrigation systems and identify coverage gaps, inefficiencies, damaged heads, and zones that no longer match the current plantings. The result is a written audit and a plan for any repairs or upgrades.
Coordination with landscape installation
For projects that include both planting installation and irrigation, we sequence the work so that the irrigation is in place before the final planting goes in. That order minimizes disruption to newly installed materials.

We match the irrigation to the landscape
The right irrigation coverage for a property depends on the soil, the sun exposure, the drainage, and what is actually planted in each area. A system designed without that knowledge will water at the wrong rates, in the wrong places, or at the wrong times. We start with the land before we design the system.
For properties where irrigation is part of a broader landscape design and installation project, we treat the system as part of the unified design rather than an add-on. That approach keeps installation disruption low, and it produces a system that supports the landscape instead of competing with it.

Common questions
Irrigation design questions
How much does irrigation design and installation cost in northern Virginia?
Irrigation costs depend on the size of the property, the complexity of the layout, the number of zones, and the soil and drainage conditions on the site. Contact us to describe your property, and we will give you a realistic estimate based on what the design actually requires.
How long does irrigation design and installation take?
Design and layout for a typical residential property can be completed within two to four weeks. Installation timelines depend on the scope of the system and the coordination required with other landscape work. We give you a clear timeline once we have assessed the site.
Can you design irrigation for a landscape that is already installed?
Yes. We frequently design and install irrigation systems for established properties, including those with existing planting beds, hardscaping, and mature trees. The design adapts to what is already on the property rather than requiring changes to existing plantings or structures.
Do you monitor and adjust irrigation systems after installation?
Yes. For properties on a maintenance program with us, irrigation monitoring is part of the ongoing care. We adjust seasonal settings, identify performance issues before they damage plantings, and make repairs as needed.
